These properties can be displayed in tables and plots through the graphical user interface; they are also accessible through spreadsheets or user-written applications accessing the REFPROP DLL Se hela listan på blog.csdn.net A surprising number of people on RG have tried to link Refprop to MATLAB with varying success. The more complex features (like user-defined mixtures) seem to be rather problematic. problem linking REFPROP to MATLAB. Learn more about refpropmatlab so, i was trying to get the value of entalphy and entrophy using REFPROP (for my multiobjective optimization), here the code: t5 = 6+273; %in kelvin. p5 = refpropm ('P','T',t5,'Q',1,'r407c.mix'); h5 = refpropm ('H','T',t5,'P',p5,'r407c.mix'); s5 = refpropm ('S','T',t5,'P',p5,'r407c.mix'); but i got some error, said that; REFPROP version: 9.1.

This MATLAB function retrieves the properties of a substance from a database and tabulates them for use in the Two-Phase Fluid Properties (2P) block. are modelled in Matlab with linked to thermophysical properties database REFPROP.

Nist told me to contact Matlab support.

REFPROP is based on the most accurate pure ﬂuid and mixture models currently available. It implements three models for the thermodynamic properties of pure ﬂuids: equations of state explicit in Helmholtz energy, the modiﬁed

I really can't understand the reason, I contacted Matlab support without getting a result, since it was told me to contact Nist.

I encountered a problem when calling Refprop software using Matlab. In this code "result = refpropm (prop_req, spec1, value1, spec2, value2, material1)", the first or second input character (spec1 REFPROP is a computer program, distributed through the Standard Reference Data program of NIST, that provides thermophysical properties of pure fluids and mixtures over a wide range of fluid conditions including liquid, gas, and supercritical phases.
